Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   42174   clinical trials with a EudraCT protocol, of which   6938   are clinical trials conducted with subjects less than 18 years old.
    The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    7. No evidence of new abnormalities consistent with LRTI on a chest X-ray performed in the 2 days before signing the ICF. If there is no chest X-ray available in the 2 days before signing the ICF, a chest X-ray must be obtained at the Screening visit.
    8. Oxygen saturation ≥92% on room air.
    9. A body mass index (BMI) ≥18 kg/m2 and ≤40 kg/m2.
    10. Negative urine pregnancy test for women of childbearing potential as defined in inclusion criterion #11.
    11. A woman of childbearing potential who is sexually active with a male must agree to use two effective methods of contraception from the date of Screening until 30 days after her last dose of study drug. Effective methods of contraception are defined as follows:
    A condom for the male partner and at least one of the following for the female subject:
    a. Intrauterine device
    b. Occlusive cap (diaphragm or cervical/vault caps)
    c. Oral, injectable, implantable, transdermal, or intravaginal hormonal contraceptive
    The above does not apply to a female subject who has a vasectomized male as the sole partner or who is of nonchildbearing potential (ie, physiologically incapable of becoming pregnant) as defined below:
    a. Has had a complete hysterectomy ≥3 months before Screening,
    b. Has had a bilateral oophorectomy (ovariectomy),
    c. Has had a bilateral tubal ligation or fallopian tube inserts, or
    d. Is postmenopausal (a total cessation of menses for at least 2 years; subjects with a cessation of menses between 1 to 2 years and a follicle-stimulating hormone [FSH] level of >35 mIU/mL will also be considered to be postmenopausal.)
    12. A male subject who has not had a vasectomy and is sexually active with a woman of childbearing potential must agree to use effective contraception from the date of Screening to 90 days after his last dose of study drug. Effective contraception is defined as a condom and at least one of the following for a female partner:
    a. Intrauterine device
    b. Occlusive cap (diaphragm or cervical/vault caps)
    c. Oral, injectable, implantable, transdermal, or intravaginal contraceptive
    For a male subject who has had a vasectomy, use of a condom will still be required.
    13. Male subjects must agree to refrain from sperm donation from the date of Screening until 90 days after his last dose of study drug.
    14. Must be willing and able to adhere to the study assessments, visit schedules, prohibitions, and restrictions, as described in this protocol.
